Abstract: A diaphragm pump comprises a carrier part, a drive motor with a drive shaft, a pump head with a pump chamber delimited by a diaphragm, and an inlet port and outlet port. The pump head is connected to the drive shaft such that the direction of oscillation of the diaphragm is orthogonal with respect to the axis of rotation of the drive shaft. A drive transmission element is mounted on the pump head and is guided in a bearing disk mounted to be rotatable eccentrically, so as to be displaceable orthogonally with respect to the direction of oscillation of the diaphragm, such that the drive transmission element generates the oscillatory movement of the diaphragm in the pump chamber during the rotation of the pump head, and as a result of the rotation a pump medium line arranged therein is alternately connected to the inlet port and the outlet port.

Abstract: Plastic profiles are produced by a pultrusion method. For this, a mold is moved periodically relative to the stationary plastic profile and said profile is held by a holding means and transported away. In particular, the starting and the stopping of the method are problematical, since a tensile stress must be applied, by which both “slack” fibers and “rigid” profiles can be drawn through the mold. The invention creates a method and a device for simple and reliable manufacture of plastic profiles. For this, it is provided that at least one cross section of a receiving space of the at least one holding means is changed along a longitudinal axis of the holding means in order to grasp a reinforcement and/or the plastic profile.

Abstract: A method and a device for fault-free production of individually curved plastic profiles. This is achieved in that the mold and the holding means are moved in opposite directions on the plastic profile, wherein the plastic profile is moved alternately by the mold and the holding means in a production direction with different movement patterns.

Abstract: A rest for a mattress support system and which serves for sensory training of a person, and a method for sensory training of a person. This rest has a multiplicity of actuatable micro-stimulating elements for producing sensory stimuli. These elements are assigned to the rest. Using a control device, the person can actuate the micro-stimulating elements during the training. Moreover, this control device serves to generate a feedback signal in response to the sensory stimuli.

Abstract: Straight plastic profiles from a plastics material and a continuous reinforcement are predominantly produced continuously in a strand, usually by the pultrusion method. As the plastic profile is pulled through a mold, only straight plastic profiles are formed in known pultrusion methods. In the production of plastic profiles using semi-finished products or complex fibrous constructions, congestion of the fibrous constructions or of the semi-finished products, and thus solidification of the material, may arise when entering the mold, such that the process has to be stopped. A method and a device for the simple production of individually molded plastic profiles is provided in that the mold is formed from at least two mold parts that in relation to the cross section of the plastic profile are split and are moved in a temporally offset manner counter to a production direction of the plastic profile along a portion of the plastic profile.

Abstract: A core (14) which is typically held in front of the mold (13) is required for producing hollow plastic objects (10). This does not allow for a transverse reinforcement (11) which is formed from a prefabricated reinforcement tube to be pulled over the core (14). A method and device is provided for the core (14) to be held behind the mold (14) when viewed in the production direction (17). In this case, the front end (15) of the core (14), which is located in front of the mold (13), remains free, such that a transverse reinforcement (11) that has been formed from a prefabricated reinforcement tube can be pulled over the free front end (15) of the core (14).

Abstract: A method for producing an object or component, which is at least partially formed from plastic, by supplying energy for solidifying the plastic of the object or component to the plastic to be solidified by at least one energy conductor, such as an optical fiber, in the component to be produced, and the solidification of the plastic can be accelerated by the direct energy introduction into the object or component to be produced.

Abstract: In the pultrusion of reinforced plastic profiles in strand form, the strands of the reinforcement are brought together in a positioning device and subsequently embedded in the plastic. The pulling of the strands of the reinforcement through the positioning device leads to an unwanted contraction and uncontrolled positioning of the reinforcement in the plastic profile. The invention envisages forming the positioning device by multiple successive positioning means, of which at least some positioning means can be periodically moved forward in the direction of production and also moved back counter to the direction of production. As a result, there is an alternating tensioning and compression of individual regions of the reinforcement. This makes exact positioning of the reinforcement in the plastic profile possible and prevents contraction of the reinforcement.

Abstract: A valve for an aerosol container has a valve plate adapted to close an axial end of the container, a valve subassembly having at least one dispensing element, a seal ring, and a compression spring, and a valve holder containing the valve subassembly and having an axially open assembly hole through which the valve subassembly can pass. A cover closes the assembly hole and is formed with an axially throughgoing cover hole through which the dispensing element projects and with which the dispensing element forms an annular and axially extending passage. A seal ring surrounds the dispensing element and is engaged between the holder and the cover. A spring biases the dispensing element axially outward against the seal ring and presses an axial outer face of the seal ring against the axially inner face of the cover. Passages extend axially between an interior of the container and the seal ring.

Abstract: An aerosol container has a mouth centered on an axis. A plastic valve plate is fitted to and tightly attached to the mouth and has a disk formed with an outlet centered on the axis. An outlet valve is carried on the valve plate and has a housing holding a movable valve element. A rigid extension is integrally formed on the disk around the hole, projects axially into the container, and forms a cavity in which the housing of the valve is fitted. A seal is fixed in the cavity between the housing and a surface of the extension forming the cavity.

Abstract: A method and device in which at least part of a mold is moved periodically relative to the stationary thin-walled plastic profile and the thin-walled plastic profile is held by at least one holding means or gripper, which comprises a core and an outer holding part, whilst the mold is moved along the thin-walled plastic profile, which is stationary relative to said mold. Plastic material objects, in particular plastic profiles, are produced predominantly in a strand, preferably using the pultrusion method. In this case, the plastic profile is pulled through a mold. As a result of the plastic profile being pulled through the mold by a take-off device, it is only possible to form plastic profiles which withstand the force or the pressing pressure of the take-off device. Consequently, only plastic profiles which comprise sufficient wall thicknesses have been producible up to now.

Abstract: Plastics articles with continuous reinforcement strands are normally produced by pultrusion. Pultrusion methods are known for producing straight or curved plastics profiles. It has not hitherto been possible for reinforced plastics articles of more complex form to be produced by pultrusion methods. The invention provides a pultrusion method in which a part of a curved plastics article serves, together with a mold (15), for the pultrusion of a reinforced plastics article. In this way, it is possible for complex plastics articles, for example a plastics pipe (10), to be produced by pultrusion.

Abstract: A plurality of cup-shaped workpieces are anodized by first securing each of them in a downwardly open position on an electrically conductive and flat workpiece frame that is then inverted such that the workpieces are open upward and lowered into a body of anodizing liquid in a treatment bath until the workpieces are wholly immersed and the frame is in contact with a horizontal rail. Thereafter the frame is moved horizontally while wholly immersed in the anodizing liquid while electricity flows between the rail and a cathode immersed in the bath below the workpieces such the liquid anodizes surfaces of the workpieces. The frame is raised out of the body of liquid with the workpieces open upward, and, while the workpieces are still above the body of liquid, inverting the frame and the workpieces so that the workpieces are open downward and any treatment liquid drains downward into the bath.
